for all \(x_0\in \mathbb {R}^2.\) 

Given \(\operatorname{deg}(A)<0\)  we have \(\operatorname{deg}(\operatorname{Div}\operatorname{Div}A)<2\) . Hence there exist \(e\in \mathbb {R}\)  and \(b\in \mathbb {R}^2\)  satisfying \(\operatorname{Div}\operatorname{Div}A=e\delta _O + \langle b,\nabla \delta _O \rangle .\)  Let \(T=A-(x-x_0)\otimes \operatorname{Div}A.\)  Then \(\operatorname{Div}T=x(\operatorname{Div}\operatorname{Div}A)\) . Accordingly, \(\operatorname{Div}T=E\in \mathcal {E}(\Omega ,\mathbb {R}^2)\)  with \(E^{0,0}=-ex_0 +b.\)  We use [1]} to establish the result.
